Abstract
A method for controlling an input clutch of a vehicle transmission during a tip-in includes using a current gear and rate of change of transmission input speed to determine a first torque modifier, if a peak or trough occurred in input speed, using the current gear and a difference between measured input speed and expected input speed to determine a second torque modifier, and changing a torque capacity of the clutch using said modifiers.
